![]() ![]() Your visual field is the area you can see when focusing on a central point. This test identifies blind spots ( scotoma) in your field of vision. Your eye doctor may have you read lines of text from an eye chart or screen. This eye exam assesses how well you can see at various distances. But doctors associate some genetic conditions with hyperopia, including:Īn eye care professional can diagnose farsightedness during a comprehensive eye exam, which may include the following tests: Visual Acuity Test There are also environmental factors that can contribute to the likelihood of developing farsightedness, but this is not well understood.įarsightedness isn’t usually part of an overarching genetic syndrome. Some of these genes may play a role in the development of the eyes. Multiple genetic variations likely contribute to the condition, each with a small effect. Hyperopic patients usually have a farsighted parent. This condition causes distant objects to appear blurred.įarsightedness runs in families. Myopia (nearsightedness) is the opposite of hyperopia, occurring when light is focused in front of the retina.This condition causes blurry vision when viewing close objects. Hyperopia (farsightedness) happens when light is focused behind the retina.Here are the differences between hyperopia and myopia: They both occur when the eye doesn’t bend (refract) light as it should. Hyperopia and myopia are two types of refractive errors. Usually, this causes distant objects to appear clearly while near ones are blurred. These abnormalities make light rays focus behind the retina instead of directly on its surface. Others may have a cornea that’s too flat. Doctors call this measurement the axial length (AL). Some farsighted people have eyeballs that are too short from front to back. With hyperopia, the shape of these structures prevents light from bending properly. This is a clear part of your eye that sits behind the iris (colored part of the eye). This is the clear, dome-shaped part of the front of your eye. Your eye has two structures that help you focus: The retina sends signals to your brain, which allows you to see. To see clearly, your eyes must bend light rays to land on your retina (the back layer of the eye). What Causes Hyperopia?įarsightedness occurs when your eye doesn’t bend light properly. Some hyperopic children may squint or rub their eyes when doing close work such as reading or homework. Children with severe farsightedness may be at risk for other eye problems, such as amblyopia (lazy eye). This is because the lens in a child’s eyes is more flexible, and they can change focus between distances more easily.Īs the eyes grow, mild childhood hyperopia diminishes or goes away completely. Most children have some degree of farsightedness, yet many don't have blurry vision. This is because the eyes work harder than they should to see clearly. They may feel tired or irritable after prolonged periods of near work. People with farsightedness often have difficulty reading up close. Blurry vision when looking at things up close.Difficulty or discomfort with close tasks like reading, writing, and working on a computer. ![]()
